A54SX32A-1BG329I

Overview

The A54SX32A-1BG329I is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 249 user-programmable I/O pins and features 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature ranges (-40°C to +85°C).

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Features deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG).

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Data path logic requiring low capacitance interconnect

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure the design tool version supports the SX-A family architecture. Check for any product discontinuation notices or end-of-life notifications prior to finalizing procurement plans.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required within a 329-pin BGA footprint. The -1 speed grade offers approximately 15% faster performance than the standard grade. Confirm that the application requires nonvolatile antifuse technology rather than SRAM-based FPGAs for immediate configuration upon power-up.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32A variant specifically targets designs needing moderate logic density with high-speed deterministic performance and robust security features against reverse engineering.
